First of all, have you tried making raw copy of that SSD? After doing that, you can try perform recovery and analysis rather than SSD itself to prevent accidental overwrite. AFAIK if you can't locate or have backup of TeraCrypt/VeraCrypt header (that store data required for decryption), usually it's considered as lost cause.
Could your team perform:
• Full forensic-level SSD image extraction (chip-off if necessary)
• Sector-level entropy scanning for encrypted volumes
• Recovery attempts for Veracrypt hidden volumes (mounting with offsets)
• File carving or keyword searches for seed phrases or wallet files
I’m happy to provide the full MacBook for recovery, or any other details needed.
